However, the heterogeneity of poultry litter and data scarcity pose challenges for predictive modeling. In this study, a robust machine learning framework was developed to predict HHV using dry-basis proximate analysis parameters (volatile matter, fixed carbon, and ash). Unlike previous studies that rely on standard datasets, this work introduces a systematic comparison of four modeling scenarios to isolate the effects of data augmentation and hyperparameter optimization. Gaussian noise–based augmentation was formulated to expand the training space, while GridSearch cross-validation optimized model parameters. Five algorithms (KNN, RF, Extra Trees, LGBM, XGBoost) were evaluated and compared against a Multiple Linear Regression (MLR) baseline. Results indicated that models on the original dataset suffered from overfitting (Test R<sup>2</sup> < 0.50) and failed to significantly outperform the MLR baseline (R<sup>2</sup> = 0.42). However, data augmentation significantly boosted generalization. Crucially, evaluation was performed on a non-augmented, held-out test set to ensure real-world reliability. The optimized Extra Trees (ET) model achieved the best performance (Test R<sup>2</sup> > 0.89, RMSE = 0.80 MJ/kg), outperforming the MLR baseline (R<sup>2</sup> = 0.64) and other ML models. Feature importance and SHAP interaction analysis confirmed that ash content is the dominant inhibitor of energy density, aligning with thermochemical principles.

Composting is an essential method; however, most optimization efforts have focused on single additives, and as a result, the potential benefits of combined additive strategies remain largely underexplored. In this review we fill this critical gap, by systematically analyzing 84 studies (2015–2025) across diverse waste substrates to evaluate how combinations of physical, chemical, biological, and conductive additives affect composting performance beyond individual additive effects. We found that strategic multi-additive combinations significantly accelerated decomposition, enhanced humification, improved nutrient (NPK) retention by ∼30-46 %, and reduced gaseous gas emission relative to single-additive approaches. Combined additive strategies such as co-applying biochar with wood vinegar reduced methane and ammonia emissions by ∼63 % and ∼36 %, respectively, compared to biochar alone, while adding zeolite (10 %) further shortened the thermophilic phase and curtailed emissions by over 50 %. Integrating nitrification inhibitors with acidifying amendments or introducing microbial inoculants alongside structural additives achieved 81–88 % reductions in nitrous oxide emissions. These synergistic effects are attributed to complementary mechanisms, including improved electron transfer capacity (15–28 % increase), enhanced substrate bioavailability (20–35 % faster degradation), pH buffering, increased aeration, and microbial niche diversification. Future research priorities include field-scale validation across climate zones, long-term soil health assessment, mechanistic modeling integrating multi-omics data, and techno-economic feasibility under uncertainty. Overall, rational additive combinations can make composting faster, lower-emission, and resource-efficient, supporting circular economy goals and climate mitigation commitments under SDG 12 and the Paris Agreement.</div></div>","PeriodicalId":253,"journal":{"name":"Biomass & Bioenergy","volume":"211 ","pages":"Article 109156"},"PeriodicalIF":5.8,"publicationDate":"2026-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146777824","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, the residue sludge (RS) obtained after removing extracellular polymeric substances (EPS) from SS is used as a precursor for the HTC process to produce RS-derived hydrochar (RSHC) as a potential biobased carbonaceous material.

Firstly, the acid hydrolysis of PLR was investigated and optimized. The acid hydrolysis of PLR realized the pretreatment of the PLR residue and the simultaneous hydrolysis of isoflavone (puerarin) derivatives and starch in PLR.

This study used cellulose as a model substance to systematically investigate the effects of nitrogen doping on the formation of biomass-derived graphitized carbon catalyzed by iron nitrate at low temperatures (700-900 °C). A combination of experimental and theoretical calculations was used to analyze the formation mechanisms. The study revealed that the type of nitrogen precursor is crucial for regulating graphitization. Specifically, g-C<sub>3</sub>N<sub>4</sub> and melamine enable the stepwise release of nitrogen at temperatures ranging from 500 to 700 °C. This process creates a carbon-rich, reducing environment that promotes the formation of active iron carbide phases with a lattice mismatch of less than 5%. This process results in a graphitization degree that is over 50% higher than that achieved in the NH<sub>4</sub>Cl/urea system. However, there is a threshold effect for nitrogen doping levels. At 0.4 mol of melamine loading, the nitrogen content reaches 6.70 at.%, but the defect density increases (D<sub>1</sub>/G = 2.9). This results in a 34.6% decrease in the graphitization degree (G/all) compared to 0.05 mol. Increasing the temperature promotes carbon framework restructuring by enhancing the release of reducing gases. However, nitrogen -induced ring defects hinder graphite microcrystal growth. Iron carbide and graphite nitrogen can jointly reduce the carbon diffusion barrier, as verified by molecular dynamics simulations. However, excessive nitrogen coverage leads to iron site deactivation. XRD, Raman, and XPS analyses confirm that the optimal graphitization effect is achieved at 800 °C with 0.1 mol of melamine. These results provide a fundamental theoretical basis for the low-temperature carbonization of biomass.</div></div>","PeriodicalId":253,"journal":{"name":"Biomass & Bioenergy","volume":"211 ","pages":"Article 109130"},"PeriodicalIF":5.8,"publicationDate":"2026-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146777823","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
